SINGAPORE, Aug 16 (Reuters) - Shanghai nickel prices surged, while a key indicator of supply shortage jumped to a decade high on Friday, amid ongoing worries about supplies disruption from top ore producer Indonesia.
Shanghai Futures Exchange’s most active nickel contract rose as much as 3.7% to 127,700 yuan ($18,132.51) a tonne, hovering near a record high hit on Monday. It ended up 2.3% at close, locking in some 10% gain for the week.
Meanwhile, the premiums of LME nickel cash over three-month contract CMNI0-3 jumped to $40 a tonne, a decade high, signalling tight nearby supplies and amid ongoing concerns over potential supply disruption from top ore producer Indonesia.
London Metal Exchange benchmark nickel fell 0.5% by 0713 GMT but was on track for its third consecutive weekly gains and has surged 51% so far this year.
Markets have been worried over a possibility that Indonesia, the world’s biggest nickel ore producer, could bring forward an export ban on mineral ore, due in 2022, to as early as this year, as it wants to boost value of exported products.
Indonesia’s President Joko Widodo said on Friday the country should push further to develop a downstream industry domestically to process natural and mineral resources including bauxite and nickel.
He is due to make a decision whether to bring forward the ore export ban.
